ESA (ember-simple-auth) The route login was not found

Does ESA suppose the app to always have login route ?

I have a link pointing to dashboard route in my navbar:

        {{#link-to 'dashboard' classNames='menu-text' }}<i class="fi-home"></i><span>Home</span>{{/link-to}}

The dashboardroute is protected:

import Route from '@ember/routing/route';
import AuthenticatedRouteMixin from 'ember-simple-auth/mixins/authenticated-route-mixin';
import { inject as service } from '@ember/service';

export default Route.extend(AuthenticatedRouteMixin, {
  session:        service('session'),
  currentUser: service('current-user')

How is it possible to redirect to login URL if I don’t have a login route neither login template as I’m using implicit grant authenticator:

import OAuth2ImplicitGrant from 'ember-simple-auth/authenticators/oauth2-implicit-grant';

export default OAuth2ImplicitGrant.extend();

and the login URL to hit is defined in application.js controller:

import Controller from '@ember/controller';
import { inject as service } from '@ember/service';
import config from '../config/environment';

export default Controller.extend({
  session:        service('session'),
  currentUser: service('current-user'),

  actions: {
    login: function() {
      let oauthUrl = config.oauthUrl;
      let clientId = config.clientID;
      let redirectURI = `${window.location.origin}/callback`;
      let responseType = `token`;
      let scope = `profile%20openid`;
                            + `?client_id=${clientId}`
                            + `&redirect_uri=${redirectURI}`
                            + `&response_type=${responseType}`
                            + `&scope=${scope}`
    logout() {

Configure the authenticate login route
